SPECIFICATION forming part of Letters Patent No. 275,559, dated April 10, 1883.

scuring the line or mark being followed in sawing.

Reference is to be had to the accompanying drawing, forming part of this specification, in which the figure is a perspective view of my improved handsaw and the method of usingit.

In carrying out my invention I attach a small pair of bellows or other air-forcing device to the handle of the saw in such manner that the same will be operated either in the act of operating the saw or by the movement of one ofthe fingers of the hand of the user that grasps the saw.

Various means for the attachment of an airforoing device to the saw might be devised; but I prefer to attach the bellows O to the handle B of the saw A by the screws to a, and to extend the bar (I of the bellows upward, so that the bellows may be conveniently operated by the forefinger of the user, as illustrated in the drawing. The exit-pipe E of the bellows is carried down near to the teeth of the saw, so that the currentof air forced from the bellows will strike the surface of the board D at or about the point where the saw-teeth rest in contact with the board, so that it will clear away the sawdust at. that point, so that the line j or mark being followed in sawing will not be covered up or obscured by the sawdust. In this manner it will be seen that the annoyance incident to the covering up of the line or mark being followed is entirely overcome Without any loss of time or trouble on the part of the person using the saw.

I am aware that it is not new to use an airoylinder and piston, the former having an outlet pointing to the heel of the hands-aw and the latter having a stem which strikes the wood which is being sawed; but

What I do claim as new is A handsaw provided with the bellows 0, attached to its handle B, having the extension-bar cl arranged upwardly within easy toward the teeth, as shown and described.
